y IMPROVEMENT IN REGULATING- DEVICE FOR GAS-BURNERS.

The Schedule referred to in thele Letters Patent and makingpart of thesame .of reference` marked thereon.

AThe principle and nature of my invention consist in supplyinggas-fixtures with a device whereby, when properly adjusted, it isrendered impossible to shut off the gas and extinguish the flame. andlight entirely without a readjustment o f the device; but whichajdjustment and readjustment are at the will and under the command ofthe operator.

Of the drawings- Figure l is a perspective view of the main body orcenter piece -of `a gasdixture, showing the extemal parts of myinventionin place.

Figure 2 is a vertical section of thesame thing showing a longitudinalsection of the parts of my invention as employed in operating the same.

Of fig. 2, a c a a is the main body of the fixture, shown with a cavityor hollow, g g.

b is the threaded opening for the supply or induction-pipe. Y

c c are the threaded openings for the. eduction or burning-pipes. y e eis a hollow cylinder screwed into the main of the fixture. at d d.

The hollow o r bore of this cylinder should be coarsely screw-threadedat point d d for the distance of half to three-fourthsfof an inch tocorrespond with threads on tubes f.l l

Tube f is a tube which passes longitudinally throughv hollow cylinders dd, and across cavity g g of the mainA body of the xtnre to the top ofthat cavity, so as to close the opening-.to induction-pipe b whendesired. This tube terminates interiorly, in an archedor hemisphencatVnipple screwed upon the end.

A short distance ybelow this nipple a flange or shoulbody ,der is formedon the tube f, on which is to rest and be secured in place by the nippleAan elastic packingn'ng, as shown at i z'.

Letters jj indicate-a mere stuiiing-box to be screwed i on to hollowcylinder d d for packing-tube f gas-.tight The letters k k mark mereprojections or handles on and near the outward end oi' tube f forconvenience in working it. A

For the fourth or third of an inch outward from these projections tube fhas a screw-threaded extension, as shown at l l.

The hollow or bore of tube f is not uniform in caliber throughout. Fromh, at the apex of the nipple,

to the apex of the conical enlargement of the bore at fm, the caliberneed not exceed one-sixteenth of an inch for four burners.

From m the caliber is conically enlarged, as shown at that point, to thesize of about one-fifth of an inch, and is thence continued of that sizethroughout the remainder of the tube.

A short distance below the base of the conical enlargement of tube f thewall of the tube is' pierced with Vsmall holes or gas-ports,corresponding in 'number with the number of eduction or burning-tubes,as shown aten n 7L. y

This tube is screwed into the main body ofthe x` ture at d d. y

Its outward extremity is provided with a stuingbox, o o, for packingregulator p, as shown between l and o. I

Regulator p is a mere cylindrical rod of sucient length and size tooccupy and fill the enlarged portion of the bore of tube j, and extendsuicient1youtward to be operated by the thumb and linger, and having itsoutward extremity provided with a thumbpiece, as shown at q.

It is secured andworked within' tube- `f'by means of a screw-threadworking in a corresponding thread in stuiing-box o, as shown at o o, andis to have a longitudinal movement in operation, from its position asshown in fig. 2, to point m in the same gure.

Its upper or inward extremity1 is obtusely conical to correspond with.'and closely tit, when screwed home to m, the conical enlargement inthebore of tube f.

My invention is more particularly applicable and useful in the lightingof billiard tables', where thegas is to be alternately let on at fullhead and partially cut oi. l

. To operate my invention and produce its intended effect, the gas islet on by so turning tube f as to withdraw the arch of its nipple orinner end from the inner opening of induction pipe b, and the packedshoulder t' from the corresponding seat 7' `on lthe inner surface ofcavity g. v

- The gas will then flow into cavity g and through pipes c to theburners, Where it is to be lighted in the usual manner. The gas will-nowburn with a full or maximum flame, and give full light.

This it will continue to do, to a great extent, though tube f be againscrewed home to h so long as regulator p occupies the position it doesin fig. 2, for the gas will still flow into cavity g through the smallerbore of fand the holes or gas-ports n.

But if,`by means of thumb-'piece q, regulator .p is now screwed inwarduntil the base of its conical point partially closes ports n'the supplyof gas to the burners (and consequently the flames).l will bediminished. By this means any degree of .diminution of the gas and damesmay be attained, or the gas may be entirely shut o, and the flame.extinguished. But when, by means of regulator p, the flames are reducedto the size at which they are to burn when not used for light,l then thedevice may be termed set for the time being. When in this condition iftube f be again withdrawn from h a full dame and light will be instantlyrestored. But by screwing it home to h again the flame and light willnot and cannot be extinguished, but the flame will be instantly restoredto lits regulated minimum size, and this without danger ofextinguishment, how quickly soever the'operation may be performed. Toextinguish the ame regulator p must be screwed home to m, or at least sofar as to wholly close gasports n.

What Iclaim as my invention, and desire to secure by Letters Patent, is-
